3GHz PMP 450i Integrated High Gain SM Polarity

Cambium C030045C002A 3GHz PMP 450i Integrated High Gain SM.  Is this polarized H/V or dual slant?  How must it be mounted for each?

When using "Cambium N000045L002A Tilt Bracket Assembly" how should it be angled for dual slant?

Spec sheet for that radio says "3 GHz : +19 dBi dual slant integrated"

So you'd mount it normal/straight... with no 45deg offset/tilt.

This is correct. There is no need to mount it at an angle, though that is possible with the Tilt Mount Bracket, in case that is necessary in some case.
